	PR fortran/25056
	* interface.c (compare_actual_formal): Signal an error if the formal
	argument is a pure procedure and the actual is not pure.

	PR fortran/27554
	* resolve.c (resolve_actual_arglist): If the type of procedure
	passed as an actual argument is not already declared, see if it is
	an intrinsic.

	PR fortran/25073
	* resolve.c (resolve_select): Use bits 1 and 2 of a new int to
	keep track of  the appearance of constant logical case expressions.
	Signal an error is either value appears more than once.

	PR fortran/20874
	* resolve.c (resolve_fl_procedure): Signal an error if an elemental
	function is not scalar valued.

	PR fortran/20867
	* match.c (recursive_stmt_fcn): Perform implicit typing of variables.

	PR fortran/22038
	* match.c (match_forall_iterator): Mark new variables as
	FL_UNKNOWN if the match fails.

	PR fortran/28119
	* match.c (gfc_match_forall): Remove extraneous call to
	gfc_match_eos.

	PR fortran/25072
	* resolve.c (resolve_code, resolve_function): Rework
	forall_flag scheme so that it is set and has a value of
	2, when the code->expr (ie. the forall mask) is resolved.
	This is used to change "block" to "mask" in the non-PURE
	error message.
